The Hohenzollern bridge in Cologne crosses the river Rheine. The bridge is used only for the trains (most heavily used railway bridge in Germany) and pedestrians. The fence between the railway tracks and pedestrians path is full of padlocks, symbolizing the true and eternal love (love padlocks). On the pano, the regional train crossing the bridge is visible, as well as the cathedral, the love padlocks, the Cologne's Triangle and the river Rheine with the Deutzer bridge.
